Viagra Professional dosage guide: how much to take and when
Choosing the right dose of Viagra Professional (Sildenafil Citrate) is the most important practical decision after starting therapy. Viagra Professional is supplied as sublingual tablet in 100mg, and the right dose for a given person depends on the indication, age, comorbidities and tolerance to the active ingredient Sildenafil Citrate.
Starting dose and titration
According to the prescribing information, most adults begin Viagra Professional at the lowest available strength of 100mg and titrate up only if symptom control is insufficient and tolerability is good. Higher doses are reserved for selected cases. Older adults, people with renal or hepatic impairment, and those taking interacting medications should usually start at the lowest dose.
When to adjust
Dose adjustment is guided by symptom response and side effect burden, not by arbitrary schedules. Sildenafil citrate inhibits PDE5, allowing the cyclic GMP produced during sexual arousal to accumulate in penile tissue, which relaxes the smooth muscle of the penile arteries and increases blood infl… If side effects are limiting at a given dose, going down a step is usually preferred over stopping abruptly. If the response is incomplete after several weeks, a higher dose can be tried under medical supervision.
